<p>The invention relates to an installation for testing the cohesion of mixed dental materials. According to the invention, the installation consists of an electro-mechanical module (A) providing the actual technical conditions for carrying out tension-compression tests, a control unit (B) ensuring the power coupling and uncoupling for the electro-mechanical module (A), the control of the motion of the mobile subassembly thereof, the change of the speed value and moving direction, as well as the control thereof, and an electronic tensiometer (C) processing the electric signal emitted by a force transducer and transmitting the same to a data acquisition and processing unit (D) which uses a special software product. The electro-mechanical module (A) has a damper (9) with a spring (18) allowing the axial force to be shock-free and resiliently transmitted to the dental material to be tested.</p> |
